OF GLASS PLATES AND SHEETS MEANS FOR ADJUSTING THE THICKNESS Filed Feb. 12, 1931 Patented Apr. 19, 1932 PATENT ()FFICE YVON BRANGART, 015' RON QUIERES,-BELGIUM MEANS FOR ADJUSTING THE THICKNESS F GLASS PLATES AND SHEETS Application filed February 12, 1931, Serial No. 515,221, and in Belgium March 18, 1930.

In the specification of Letters Patent N 0. 1,819,222 granted to me on the 18th August, 1931, I have described out means for regulating the thickness of cast glass plates and sheets, in which the so-called calibrating roller governing said thickness is supported on either side of the casting table by a hearing mounted on a carriage and adjustable in height relatively to said table, to adjust 1' the height of the roller above the same.

The improvements now described refer to further constructional embodiments of said means, respectively illustrated in Figs. 1, 2 and 3 of the accompanying drawings.

In one embodiment, shown in Fig. 1 of the drawings, the bearing (Z carrying the journal -0 of calibrating roller a above the casting table 5, is mounted concentrically to the joint of two compass arms 1" resting on table b by means of wheels The axles of said wheels are connected by apair of inversely threaded tensioners g, upon which doublethreaded nut k is screwed. To move the roller a towards or away from table I), nut h is manipulated to open or close the compass arms 1'.

F ig. 2 shows another embodiment in which journal (Z is set in a slide-block s, which may be raised or lowered in a vertical slot t of carriage i by turning screw u, to adjust the height of roller a above casting table I). Carriage c rests on said table through casters Z.

In the thirdi'orm shown in Fig. 3, journal (Z is raised or lowered by causing it to ascend or descend an incline o by means of a screw w meshing with an internally threaded slide m. The incline o is integral with the carriage z fitted with roller casters Z and it comprises a graduated scale y, by means of which the exact level of bearing d may be set and the thickness of the glass plate or sheet between roller a and table 6 :5 may consequently be predetermined.

Possible modifications of these three embodiments of the invention may, of course, be effected without departing from the principle of the invention.

I claim:

1. In combination with a casting table, a calibrating roller, a bearing for said roller,

a carriage on said table having an upward guideway, said bearing being slidably mounted in said guideway, and a screw jack in said carriage for lifting and lowering said bearing in said guideway.

2. In combination with a casting table, a calibrating roller, a bearing for said roller,

a slide carrying said bearing, a carriage on said table, an inclined guideway on said carriage, said slide engaging said guideway, and means for moving said slide along said guideway.

3. In combination with a casting table, a calibrating .roller, a bearing for said roller,

a slide carrying said bearing, an inclined guideway on said carriage, said slide having an inclined bottom face engaging said guideway, screw means for moving said slide along said guideway, and a graduated scale on said guideway adapted to cooperate with one edge of said slide.

YVON BRANCART.
